[GAMEPLAY] Inner Turrets give too much shield.

A few days after the release of patch 5.5, where non-mid lane inner turrets' shields were reduced to 30, I found that, while farming under the top-inner turret, the enemy Kalista's shield was a lot higher than 30. I checked her build/buff row, and saw no shield item/buff. This was very annoying, as this prevented me from an easy tower dive. This same thing happened to me later on the bottom side inner turret, where the Janna's shield was more than 30, and had not E'd herself. This also happened to me a few times, and I'm sure it is a bug. I expected it to be fixed in 5.6, but I found it was not. I feel like this could really change games and if you could remove this bug as quick as possible, that'd be great!
